Patented Oct. 1, 1929 I WILLIAM H. MILLER, 01? LOGAN, OI-I IO, ASSIGNOR TO THE LOGAN FOUNDRY AND MACHINE COMPANY, OF LOGAN, OHIO CLEANING-OUT MACHINE Application filed August 20, 1927. Serial No. 214,411.

The present invention relates to a structure whlch 1s known 1n 01]. well dlstrlcts as a cleaning out machine.

- The purpose of the invention is to provide.

a dependable structure of this class which can be substituted for the unreliable wooden rigs now employed extensively for this work in oil fields.

Myprincipal aim isto providea machine for this purpose which is characterized by such indispensable features as inexpensiveness in manufacture, compactness and convenience in arrangement of parts, and efficiency in operation.

The details and their relative arrangement and association, upon which the alleged novelty is based, will become more readily apparent from the following description and drawings.

In the drawings Figure 1 is a perspective view of the complete machine as constructed in accordance with the present invention.

Figure 2 is also a perspective view observing the power supply end of the machine.

Figure 3 is a top plan View of the same.

In carrying out the invention, I provide a support which comprises a pair of substantially duplicate end frames 4, these being preferably in the form of metal castings of appropriate dimensions and each frame including a pair of substantially V-shaped uprights 5 and 6 respectively. (See Figure 2 These uprights are provided at their upper ends with suitable bearings and a driven shaft 7 is mounted for rotation in one set of bearings on the uprights 5 while a driving or power shaft 8 is mounted in the bearings in the remaining uprights 6. It will be noted that the drive shaft is somewhat longer than the driven shaft 7 and extends beyond one end frame and has the extended end portion 9 located in a bearing in a supplemental standard or upright 10. A pulley 11 is carried by this extended portion of the shaft and is adapted to be driven through the medium of a belt (not shown) from any suitable source of power.

It will be further noted that a pair of angle irons 12 and 13 are connected to the base portions of the end frames as shown in Figure 2 and serve to maintain these frames in spaced parallelism. The iron 12 is extended as shown in Fig. 2 to maintain the'standard in proper relationship to the adjacent end frame.

Directing attention now to Figure 3 in particular, it will be observed that pair of independent drums 14 and 15 are mounted for rotation upon the shafts 7 and 8 respectively. The large drum is known as the cleaning out drum, as distinguished from the smaller or sand reel drum 15. The drum 14: includes a body portion 16 having a circular head plate 17 at one end and a complemental flanged head plate 18' at the opposite end. The flange of the last named head plate constitutes a braking surface over which a brake band 19 is placed. As shown in Figure 1 the inner end of this band as indicated at 20 is an- 7 vchored upon the angle iron 18. The opposite end of the band is c'onnected with a crank 21 forming a part of an oscillatory rock shaft 22 which is operated by a .control rod 23 whose operating end is located within con venient reach of the attendant. At this time, attention is directed to a clutch 24L of suitable construction which serves to provide a driving connection between the drum 14c and the driven shaft 8. Located on one side of this clutch and on one end frame isa perch or bracket 25 with which a yoke 26 has pivotal connection. The opposite end of the yoke is connected with one arm of a bellcrank 27 which is also pivotally mounted on the last 5:5 named end frame. An operating rod 28 is provided for the bellcrank. Thus, we have individual operating deviees for the clutch and brake band.

Considering now the aforesaid small drum so 15, it will be observed that it also comprises a disk-like head 29 at one end, a central body 30, and a complemental head 31 constructed to accommodate a separate brake band 32. Again, the brake band is permanently an- 95 ehored at one end as at 33 to the angle if iron 12 (see Figure 1) while at the opposite end it is connected with a crank 34 on a rock shaft 35 journaled for rotation in appropriate bearings 86 and 37. Incidentally; the

last named bearing 37 is on the stand or standard 10. The adjacent end portion of the rock shaft extends upwardly at 38 as indicated here and an adjustable connecting member 39 is connected therewith. The opposite end of the member 39 is connected with the longer arm of an especially designed bellcrank 40. The short arm of this bellcrank 40, which is pivoted on the end frame 4 as shown in Figure 3 is connected, through the medium of a link 41 with a pivotally'mounted yoke 42 which serves to operate the clutch 43 for the drum 15. A reach rod l4: is connected to the long arm of the bellcrank 40, thus r" serving to provide a mean for simultaneously operating the brake and clutch. In other words, as soon as the clutch is thrown out, the brake band is tightened to stop further rotation of the drum 15.

From the foregoing description and drawings it will be observed that Ihave evolved and produced a machine having located in close proximity a pair of individual drums, a larger drum adapted to accommodate a correspondingly large line usedin cleanout work, and-a smaller'drum to operate as a sand reel drum to take care of the bailing of the sand and different sediments in the oil well. Of course, both of'these drums are built along the same line but are really essential for efficient work, and it is believed to be advantageous to have them mounted on the same supporting frame in close proximity for convenient manipulation. The structure is also advantageous in that it permits the brake on the sand wheel to be applied substantially simultaneously with the disengagement of the clutch, thus giving the sand reel what is known in the oil field as a backbrake action. The use of a single distant controlled reach rod for the simultaneous operation of brake and clutch promotes convenience of operation of the attendant.

The structure herein shown is also advantageous in that it provides a large drum such as can be employed as a bull wheel shaft. In

ddition, the constantly driven gearing can be employed for operating a pump jack, at which time the clutches for the drums can be thrown out so as not to interfere with the transmission of power at this time.

Motion is transmitted from the drive shaft 9 to the driven shaft 8 by a small pinion do on the shaft 9 meshing with a large gear 46 on the shaft 8. It might be stated in this connection that the gear 46 carries an eccentric pin d7 for a pitman (not shown) used to operate the pump jack.

It is believed that the description and drawings will suflice to enable persons skilled in theart to which the invention relates to obtain clear understanding of the advantages and method of operation. and use. Therefore, a more lengthy description is thought unnecessary.

Minor changes in shape, size, and rearrangement of parts coming within the field of invention claimed, may be resorted to if desired.
